Hmmm. The last part of my reply didn't get posted. I might have deleted it or something. Anyhow, I also wrote that Jolly tiles can also refer to tiles with mitered edges. That allows two jollys to turn a corner. So the term can be used in different ways. I'm not enough of a tile guy to know if one description is more correct than the other.

Walker Zanger 6th Avenue has a white gloss but not sure how white it is as I was focused on finding a blue. This is Walker Zanger's more "affordable", "quick ship" line from what I've been told and more affordable than most Pratt & Larson for example which I also looked at. (I'm using the WZ pale sky gloss in a 6" hex for a bathroom project that has yet to begin.) It has lovely mouldings and does have bullnose pieces. However, the mouldings are expensive, even in this more "affordable" line. Luckily I don't need any of the molding pieces. https://www.walkerzanger.com/collections/products.php?view=mat&mat=6th+Avenue&coll=6th+Avenue You could also consider Sonoma Tilemakers Stellar Quickship Collection which is also "affordable". In the Steller Quickship line, there is a "Blanco" gloss which is white (can't remember how white it is though) and there are lovely mouldings and bullnose to choose from. My mom used the 4x8 bossy gray from this line for her bathroom backsplash, including bullnose pieces. https://sonomatilemakers.com/stellar-quickship/ If you have more money to spend, Sonoma Tilemakers' regular Stellar line (not the quickship) has "Pure white" in addition to "Blanco" and even more liners and mouldings to choose from. https://sonomatilemakers.com/stellar/ To give you an idea of pricing, for me, the WZ 5th avenue 6" hex is approx $24/sq ft (w/o contractor discount) or $19.50/sq ft w/discount. The WZ 3x6 bullnose is approx $9.50 per piece (w/o discount) and base moulding is approx $21 per 4x8.5" piece (w/o discount). Sonoma Stellar Quickship (for the bossy gray color at least) was approx $18/sq ft for the 4x8's (w/o contractor discount or $14.50 w/discount) and $25.50/sq ft for a non-quickship glaze (w/o contractor discount).

Thank you both for confirming my suspicion. Skippack - the 12X24 is plain white. I looked at a few other tiles in a longer bullnose but their white looks different. It is amazing how much variation there is in "plain white" tile. :O I will look into the Schluter edge that I think will look better than 4 bullnose tiles per every one 12X24 tile. I agree that it would be too "busy" vs the simple, clean 12X24 shower tile look I'm going for.

Has anyone had the Schluter on the wall for any length of time? I'm just a bit concerned about using that, because I had an old 70's style kitchen with chrome trim on all the formica countertops (prior to our renovations), and it looked awful, and it was pitted in spots, etc. I'm wondering how a metal piece will do in a wet environment like a shower? @Carrie B If you do have some photos of it you can share, that would be great.
